AoS Summoning Question

In a matched play game you can have X number of Heroes, Monsters, etc. for whatever max points you decide to use. My question is; through summoning, can you get more of whatever unit type than what the rules allow for your pitched army?

Ex: if I were doing a 1000 pnt battle and could only have two monsters in my army list, could I use summoning points to possibly summon in a third monster?
